I just bought a used basket and put it on my bicycle, then lined the bottom with cardboard and a beach towel. Norton jumped out the first time I put him in, but he stayed in the second time and I took him for a short ride. He appeared to like it.

I suspect that soon the word "bike" will elicit the same rambunctious manic behavior that "swim" did when we had our pool and "walk" does now. That's his head in the lower left corner.
